Raymarine 37STV Satellite TV Antenna System, 37 cm Dish, Built-In GPS, Dual Band, HD Compatible

Overview

The Raymarine E70456 is a 37STV marine satellite TV antenna system for keeping Ku-band TV reception on smaller cruising and fishing boats where radome space is limited. It uses a 37 cm reflector inside a compact dome and is suited to vessels around 7.6 to 10.7 m, or 25 to 35 ft, with a 9.0 to 30.0 V DC power requirement for installation on common 12V and 24V DC systems.

This system automatically searches for and tracks satellite TV signals while the boat is moving. Wide Range Search helps the antenna acquire a signal quickly, while Dynamic Beam Tilting compensates for heading, pitch, and roll so the picture remains more stable underway. The antenna supports Ku-band reception from 10.7 to 12.75 GHz, with RHCP, LHCP, vertical, and horizontal polarization support.

The radome measures 44 cm high by 43 cm in diameter and weighs about 9 kg, making it a practical fit for hardtops, radar arches, and other topside mounting points where larger satellite domes are not suitable. The housing carries an IPX6 water ingress rating for exposure to spray and washdowns, and the Antenna Control Unit includes built-in Wi-Fi, built-in GPS interface support, and dual RF output.

Key features

• 37 cm reflector with a compact 43 cm radome diameter for boats with limited topside mounting space.
• Recommended for vessels around 7.6 to 10.7 m, or 25 to 35 ft, including small cruisers, express boats, and fishing boats.
• Wide Range Search helps the antenna find and lock onto a satellite signal with less waiting at startup.
• Dynamic Beam Tilting compensates for vessel heading, pitch, and roll while underway.
• Ku-band reception from 10.7 to 12.75 GHz with support for circular and linear polarization formats.
• 9.0 to 30.0 V DC input suits typical 12V and 24V marine electrical systems.
• IPX6 water ingress rating for marine spray, rain, and routine topside washdowns.
• Single antenna-to-ACU cable path helps reduce installation complexity.
• Built-in Wi-Fi lets compatible phones, tablets, and computers connect to the ACU for monitoring and setup.
• CE and FCC approvals support use in properly installed marine electronics systems.

Installation and setup

The antenna should be mounted with a clear view of the sky and away from structures that can block the signal, such as masts, radar arrays, tall arches, or metal deck hardware. The compact dome size helps when working around crowded hardtops, but the mounting point still needs enough strength for the 9 kg antenna and enough clearance for service access.

The Antenna Control Unit is installed inside the boat and connects to the antenna with a 15 m RG6 RF cable. The ACU requires DC power and typically draws 30 W, with a maximum consumption of 50 W, so the circuit should be planned with suitable protection and cable routing for a marine electronics installation.

Compatibility and onboard use

This 37STV system is a good match for boat owners who want satellite TV on compact vessels without moving up to a larger dome. It is especially useful for coastal cruising, weekend trips, marina stays, and fishing boats where entertainment at anchor or dockside matters but mounting space is limited.

Reception depends on satellite coverage, service provider setup, antenna placement, and the vessel location. For the best result, plan the installation around a clean sky view and confirm the satellite TV service area for the regions where the boat will be used.

Maintenance and care

Keep the radome clean and free from salt buildup, bird residue, wax, and heavy grime that can affect signal performance. A fresh water rinse after saltwater use and a mild boat-safe cleaner are usually enough for routine care.

During seasonal service, check the mounting hardware, cable strain relief, and exterior cable runs for movement, chafe, or corrosion. Any satellite TV antenna works best when the dome stays secure, the cable path remains dry and protected, and the power connection is kept in good condition.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
